Reliability Data Sheet
Description
The following cumulative test results have been obtained
in accordance with the latest revisions of JEDEC standards
Avago tests parts at the absolute maximum rated condi-
tions recommended for the device. The actual perfor-
mance you obtain from Avago parts depends on the
electrical and environmental characteristics of your appli-
cation but will probably be better than the performance
outlined in Table 1.

Failure Rate Prediction
The failure rate of semiconductor devices is determined
by the junction temperature of the device. The relation-
ship between ambient temperature and actual junction
temperature is given by the following:
T
where T
θ
P
The estimated MTTF and failure rate at temperatures
lower than the actual stress temperature can be deter-
mined by using an Arrhenius model for temperature
acceleration. Results of such calculations are shown in
the table below using an activation energy of 0.43eV
(reference MIL-HDBK-217).
